The screen mounting and securing means, contemplated by the present invention, is particularly adapted to screens of the type illustrated and described in my copending applications, Serial N 0. 75,133 and Serial No, 75,134, filed April 18, 1936, and entitled respectively Window screen, and metal screen and method of manufacture. Therefore to illustrate the present invention there is shown in the drawings, a screen having the characteristics of the frames shown in said prior applications. It is to be understood, however, that the present invention is equally applicable to is necessary, particularly where the windows are above the first floor.

To overcome the above objection, the present invention provides a new and novel form of supporting means for an outside screen which will permit a mounting and a securing of the screen, and also a perfect adjustment thereof upon the window frame by an operator at the inside of the window frame.

As shown in Figures 1 and 2 of the drawings, the invention contemplates the provision of outwardly extending brackets II] at each side of the window frame near the upper corners thereof and a pair of outwardly disposed bracket engaging supports II at the upper corners of a screen frame Ii! which carries a spline secured screen fabric I3.

As illustrated in Figure 3 of the drawings, the brackets til have a flange I4 by means of which they may be adjustably secured upon a sash retaining strip I5 or other portion of the window frame, and disposed in spaced relation and extending out of the window opening, the brackets IE! have a support engaging portion I6 with an upstanding end I? over which the supports II upon the screen frame I2 are adapted to be hooked.

As shown in Figure 4 of the drawings, the bracket engaging supports I I have a right-angled portion I8 with a slot I9 through which the upstanding end II of the bracket II] is adapted to project. In this latter figure of the drawings. and as is further illustrated in Figure 5, the screen frame I2 is shown as recessed between the points 23 and 2I for a depth equal to the thickness of the bracket I0, so that the screen frame IE will rest fiat against the sash securing strip I5 when the screen is positioned within the recess formed thereby in the window frame.

In order to insure a tight fit between the screenframe and the sash securing strip I5 of the window frame, the upstanding portion II of the bracket If) is disposed at a distance A from the surface of the sash retaining strip I5, as shown, which is equal to a distance B, which is the dimension from the inside surface of the screen frame I2 and the outside surface of the rightangled portion I8 of the bracket engaging hanger I I. To provide for the proper vertical positioning of the screen within the window frame opening, the bracket III also has a horizontal surface 22 which is disposed a distance C below the upper limit of the screen receiving recess of the window frame, and the upper end of the slot I9 of the bracket engaging hanger II is positioned a distance D below the upper outer edge of the screen frame, which distance D is equal to the distance C. With this general form of bracket and bracket engaging support, it will be seen that the screen I3 and its frame I2 may be projected edgewise through the window opening and then with the screen in its outswung position, the bracket engaging supports I I may be placed upon the brackets It by an operator from within the window opening, after which the screen and its frame I2 may be permitted to pivot down and into its normal vertical position within the window opening, as shown in Figure 2 of the drawings.

To provide for a vertical adjustment of the screen within the window opening after the screen is in place, and particularly to insure a close fit along the bottom edge thereof with the sill of the window opening, the brackets I are made so that they can be adjusted vertically within the window opening. This adjustment in its simplest form is provided for by a slot 23 in the strip engaging flange I4 through which a securing screw 24 is passed. This slot and screw arrangement, as will be readily seen, will permit the brackets II] to be adjusted from the inside of the screen, and after the screen has been positioned upon the brackets I0. After the brackets II! have been properly adjusted, so as to produce the desired positioning of the screen within the window opening, the screw 24 is tightened upon the bracket III and an additional screw 25 is then applied to further secure the bracket II) against any further vertical movement in the window opening.

In the manufacture of metallic window screens of the character described, it is particlularly important that the assembly of parts be reduced to the simplest form, and for convenience and safety in shipment it is desirable that the screen frames be shipped without the bracket engaging supports or other securing means, as these supports, because of their nature and projection from the screen frame, easily become bent or otherwise damaged. Therefore the bracket engaging supports are constructed in accordance with the present invention so that they may be shipped separately and then easily and readily applied to the screen frame I2 in a simple manner and without special tools by an operator at the point where the screens are to be used. A number of types of bracket engaging supports and means for attaching same to the screen frame I2 will be described in detail hereinafter.

As shown in Figure of the drawings, the bracket engaging support II is attached to the side of the screen frame I2 by means of a tongue 26 which projects into the side of the screen frame I2, and a screw 2i which projects into the corner of the screen frame channel at the point where a screen securing spline will not interfere therewith. In this particular embodiment of the invention, the screen frame I2 has a flange 28 which is turned back over the outside of the support I I at the edge of the recessed portion 202I upon the inner face of the screen frame I2.

Before passing on to a description of the other forms of bracket engaging hangers and modes of adjustment, contemplated by this invention, reference is now made to Figures 6, '7, 8 and 9 of the drawings, which show various cooperating means for securing the bottom of the screen frame I2 within the window opening. Like the brackets I0, all of these securing means are so constructed and arranged as to be effectively applied in securing the window screen by an operator at the inside of the window opening, and therefore, as has been pointed out above, it is possible with the supporting brackets and hangers described, and with the securing means to be now described, to place and secure the screen upon the outside of a Window frame from within the window opening.

As shown in Figure 6 of the drawings, this securing means comprises a hook-like member 29 which is hooked around an outwardly extending flange 30 upon the screen frame I2, and is retained in a screen locking position by means of an upstanding abutment 3| which is secured upon the window sash by means of a screw 32. The outer hooked end of the member 29 is passed through a groove or notch cut in the outside edge of the flange 30. This form of securing means permits a convenient unlatching of the screen, so that it may be readily removed from the inside of the window opening when required.

As shown in Figure 7 of the drawings; the

screen frame it is shown as secured at its bottom by means of a flanged plate 33 which is likewise secured upon the sill inside of the screen by means of ascrew 34. In this arrangement the flanged plate 33 has an upstanding end 35 which is insertable through a groove formed in the bottom of the flange til upon the screen frame I2. With this arrangement it will be readily seen that the screw 54 may be removed and applied by an operatorat the inside of the window screen.

In Figures 8 and 9 of the drawings, there is shown a further modified form of screen securing means that employs an ordinary hook and eye, and which can be readily applied to the screen and sash by an operator, without special tools, at the location where the screen is being installed. In accordance with this embodiment of the invention, the flange of the screen frame l2 has a slot 36 through which a member 31 extends, the member 3'5 having extending ears 38 at its outer edge to prevent its being pulled through the slot 35. At the inside of the screen the member 3? is provided with a hole 39 through which the eye of a'hook 45 is looped. With this arrangement the parts may be readily disassembled by disengaging the hook M from the member 31, which can then be removed from the flange 35 of thescreen frame I2. In assembling the parts, the above operations will be reversed, after which the eye of the hook Ml may be bent closed. i

As shown in Figure 9 of the drawings, the hook lil is adapted to cooperate with an eye 4| upon the window frame sill, where the hook 40 is accessible to an operator at the inside of the screen.

"mg downwardly depending Since it is the purpose of the present invention to provide a screen supporting means which is simple in construction, inexpensive to manu facture, and one which can be readily applied to a screen in the field without the use of special tools, resort is had to various arrangements of interlocking tongues and slots. In some of these arrangements the tongues are adapted to be bent into their final positions, and in others the tongues are pre-formed so that they will readily engage cooperating slots formed in the screen frame. Several additional modifications of the screen supporting means constructed in accord ance with the present invention, will now be described in connection with the remaining figures of the drawings.

In Figures 10 and 11 of the drawings, there is shown a modified form of bracket engaging sup "port, designated by the numeral 42, which is adapted to be readily attached to the side of the screen frame l2 by a tongue and slot arrangement. In the embodiment shown, the support 42 has three inwardly projecting tongues 43 havends M. These tongues 53 with their downwardly depending ends M, are adapted to be projected through correspondingly located slots in the outside wall of the spline receiving channel of the screen frame i2, after which the bracket engaging support 42 is moved downwardly to interlock the downwardly depending ends M with the screen frame, where an offset tongue 45 at the top of the support 32 is adapted to engage in a horizontally disposed slot 46 form-ed in the screen frame, as shown. The tongue 45 may be such that it will snap into the slot 46, when the support 42 is in its final position, or it may be bent in as a separate operation.

In Figure 12 of the drawings, there is shown a bracket engaging support 41 which is adapted to be secured upon the screen frame l2 by means of tongues 48 and 49 formed upon the outer wall of the spline receiving channel of the screen frame l2. In this embodiment of the invention, the tongues 48 and 49 are arranged in line along the outer surface of the screen frame, and at the inside of the screen frame the support 4'! is secured by bending back the flange 3B of the screen frame, as indicated at 50 in this figure of the drawings. The tongue 48 passes through a slot 5| in the support 41 and the tongue 49 is disposed in a notch 52 formed along the outside edge of the support 41. i

Asa further modification of a screen support constructed in accordance with this invention, there is shown in Figures 13 and 14 of the drawings, an arrangement wherein a support 53 is secured upon the outside surface of the screen frame it. In this arrangement the screen frame i2 is provided with two oppositely and diagonally disposed slots 54 which extend into the opposite walls of the spline receiving channel of the frame l2 at the outer side thereof, and the support 53 is provided with similarly disposed and coop-- erating reentrant tongues 55 which, by a rotating movement of the support 53, can be placed into interlocking engagement with the slots 54. After the tongues 55 have thus been rotated into engagement with the slots 54, the support 53 is secured against displacement by means of a threaded securing means 56 that extends intothe spline channel of the frame I2 at the corner thereof, where the rounded spline, designated by the-numeral 51, will not interfere therewith.

In addition to the above various forms of bracket engaging supports, the present invention alsocontemplates a modified form of securing bracket which, like the bracket l0, provides for an adjustment of the screen within the window' opening from a point inside of the screen after the same has been positioned within the window opening. As here shown, this: bracket comprises a right-angled member 58 which is secured withinthe window opening by means of a screw 59 and an outwardly extending adjustable portion til which projects outwardly, where it is engageab-le by a bracket engaging support 6! attached to the outside surface of the screen frame 12. In. this arrangement the adjustability of the portion Gil is provided for by a slot 52 in the member 58 through which a screw 63 carried by the member 60 passes. It will here be seen that after the screen support 6| has been engaged upon the outwardly extending portion 55, the latter portion, by a release of the screw 63, may be adjusted vertically to permit any desired positioning of the screen frame I2 within the window opening. In connection with this type of adjustable support, it will be understood that the bracket 6! may be attached to the screen frame l2 in one or more of the manners above described, or it may be attached, as shown in Figure 15 of the drawings, by means of screws 54. If the bracket 6| is positioned along the spline receiving channel of the frame l2, it is contemplated. that the spline, here designated by the numeral 51, may be flattened or cut away at this point, as at 65, to provide a clearance for the end of the screws 64.

As shown in Figure 16 of the drawings, the bracket engaging support 6| has a horizontally disposed slot 56 which passes over and behind an upwardly curved end 61 of the adjustable member 60.
